To all whom it may concern Be it known that l, DANrEL Soi-roms, citizen ofthe United States, residing at Chr cago, in the county. of Cook and State of Illinois, have invented a certain new and useful improvement in Power-Transmission Mechanism, of -which the following is a full, clear, concise, and eXact description, reference being had to the accompanying drawings, 'forming a part et this specification, this application loeing a division of my original application Serial. No. 830,580, tiled April 9, 1914.

liiy invention relates to power transi iission mechanism` and has been embodied in a Wind mill strutture, though the invention is not to oe limited to any particular use to which it may be put. v

The application of the inventionto a Wind mill structure is disclosed in my original application Serial No. 830,580, `filed April 9, 1914, of which original application the presentapplication is a division.

One feature ci my pres-ent invention may loe generally described as comprising a pair of gears in mesh With another pair of gears driven by the i'irst, the gears of the second pair having shafts that are in telescoping and relatively rotatable relation.

.in accordance with another feature of my invention, which' additionali'eature is pret erably employed in a mechanism. embracing ythe first feature of the invention, the gears of one pair have formations for maintaining the spacing therebetween and which formations are adapted for interengagement, upon relative rotation of the gears having the same, in order tol maintain such spacing, the remaining gears operating to preserve the interengagement oi said formations.

is l have practised the invention the irst pair of gears yare'driven by the Win-fi 'wheel of a wind mill 'While pitmen establish. power transmitting connection between the gears of the second pair and the load or pump rod of the wind mill. means of my invention there is an even division of" the driving power between the two sets 'of meshed gears and the pitrnen since the gears which are coupled with the pitmen are free to move relatively in their planes to compensate for inaccurate alinement of the. gear teeth.

The accompanying drawing illustrates the adaptation of my invention to a Wind mill structure, Figure l. being a plan `view oi so much of the structure as is necessary to an understanding of the invention; Fig. 2 a sectional elevation on line 2 Q of Fig. l; Fig. 3 an axial sectional vieu' through the gearing of my invention: and Ll a side view of the gearing.

Lilie parte are indicated by similar characters of reference throughout the different figures.

The portion of the Wind. mill structure illustrated includes a tower 1 which termi# natos in an upright stationary tubular column 2 whose reduced upper end constitutes an upright shaft that 'aords an upright axis about which the Wind mill head i may turn upon a step hearing ring 5 supported upon the tnhular column portion The shaft 10 yoie the prime mover, in this instance the Wind Wheel 11 of a Wind mill, is journaled upon the mill head and carries a'pair of upright pinions or gears 152 for driving the upright pump or load rod 13.

A pair of upright transmission gears 14 in mesh with the pinions or gears 12 and are journal-ed Within a bearing 15 carricci by the head e llitnoen 1G connect the gears 1v1 with the upper end of thc load rod i3 A stirrup 17 is fixed upon the upper end of the load rod and carries a shaft 18. v The stirrup 19 engages and guides the rollerQO on the shaft 18. The gears l2 are relatively fixed and,-to insure the even division of driving power between the tivo sets oi meslied gears and their pitmen, the gears 1li of the other pair are free to more relatively in their planes 'to compensate for inaccurate alinement of the teeth of citheror both pairs` of gears. The gears Hf are therefore provided vvith shafts Q1 and 22 that are in telescoping and relatively rotatable relation, the outer sleeve shaft 22 being directly ,supported by the hearings l5 and itself constituting a bearing 'for the inner shaft 21 which may also he hollow it desired. The relative end play of the gears 1i is prevented by the preferred form of interengagement of the shafts 21 and 22 shown in Figs. 3 and 4. In the structure oi' these figures 'the gear shaft 2l. carries an oblong end 211 which. may loe positioned to slip through an oblong continuation 221 of the bore of shaft 22 Whereafter said shafts are relatively rotated to bring the fiat end 211 in some such relationship as that illustrated in Fig. 4 and which relationship is substantially maintained by the intermeshing of the gears la with the gears 12.

While I have herein shown and particularly described the preferred embodiment of my invention l do not wish to be limited to the precise details of construction shown as changes may readily be made Without departing from the spirit of my invention, but- Having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. Power transmission mechanism including a motor driven shaft; a reciprocating upright load rod; a pair of gears driven by the motor driven shaft; a second. pair of gears which drive the load rod and which are driven by and are in mesh with the first; and pitmeh that establish power transmitting connection between the gears of the second pair and the load rod, the gears of the second pair having shafts one of which enters the other and which shafts are in relatively rotatable relation.

2. Power transmission mechanism including a motor driven shaft; a reciprocating upright load rod; a pair of gears driven. by the motor driven shaft; a second pair of gears driven by and in mesh with the first; and pitmen that establish power transmitting connection between the gears of the second pair and the load rod, the gears of the second pair having shafts one of which. enters the other and which shafts are in relatively rotatable relation, the gears of the second pair having formations for maintaining the spacing between these gears and adapted for interengagement, upon relative rotation of these gears, then to maintain such spacing, the remaining1 gears serving by meshing with the others to maintain the space preserving interengagment of said formations.

3. Power transmission mechanism including a motor driven shaft; a reciprocating upright load rod; a pair of gears driven by the motor driven shaft; a second pair of gears driven by and in mesh with the first; and pitmen that establish power transmitting connection between the gears of the second pair and the load rod, the gears of the second pair having formations for maintaining the spacing between these gears and adapted for interengagement, upon relative .rotation of these gears, then to maintain such spacing, the remaining gears serving by meshing with the others to maintain the space preserving interengagement of said formations.-

4. Power transmission mechanism including a motor driven shaft; a pair of gears driven by the motor driven shaft; and a second pair of gears which' drive the load and which are driven by and are in vmesh with the rst pair of gears, the gearsof the second pair 'having shafts that are in telescoping and relatively rotatable relation.

5. Power transmission mechanism including a motor driven shaft; a pair of gears driven. by the motor driven shaft; a second pair of gears which drive the load and which are driven by and are in mesh with theiirst pair of gears, thek gears of the second pair having formations for maintaining spacing between these gears and adapted for interengagernent, upon. relative rotation of these gears, then to maintain such spacing, the remainingl gears serving by meshing with the others to maintain the space preserving interengagement of said formations.

ln witness whereof, lf hereunto subscribe my name this 3rd day of September A. D., 19M.
